T all whom t ma concern:

Be it known t at I, ALFRED H. RUDGE, a citizen of the United States, residing at Newark and State of New Jersey, have invented certain new and useful Improvements in Chat-Separators for Concentrat ing-Jigs and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved chat se arator for a concentrating jig, and one object of the invention is to provide a separator so constructed that it may be associated with a jig of a conventional construction and not require alterations in the construction of the jig', the separator being provided with oneor more outlets for registering with the outlet or outlets of the jig.

iAnother object of the invention is to so construct this separator that the concen# trates may be very thoroughly separated from the tailings or refuse, the concentrates passing under the inner wall of the separator and the tailings passing out of the jig `compartment together with the waste water.

Another object of the invention is to so `construct the separator that the concentrates along the sides of the compartments or cellsaloove the supporting screen and the concentrate pass out through the outlet opening formed in` the enlarged housing forming part of the separator.

`Another objectof the invention is to so construct the separator that it may be formed from sheet metal.

Another object of the invention is to so construct the separator that the same principal of the outer wall engaging the screen and carrying the supporting lip for engaging the wall of the cell, the inner wall terminating short of the lower end of the outer wall and the enlarged housing having the outlets for re istering with the usual outlets of a jig cl, may be employed in connection with separators for use 1n different types of Another object of the invention is to provide a separator which will be very simple in construction, easy to install and Ilot liable to become choked when in use.

This invention is illustrated in the accompanying drawings, wherein:

Figure l is a transverse sectional view through a concentrating jig of a conventional construction showing separators of the improved construction in use.

Fig. 2 is a vertical longitudinal sectional view taken through the structure of Fig. l.

Fig. 3 is a transverse sectional view through one of the cells of the concentratin jig.

igs. 4 and 5 are perspective views of the type of separator shown in use in Fig. l, Fig. 5 showing the separator when looking at the outer face and Fig. 4.- showing the separator when looking at the inner face thereof.

Figs. 6 and 7 are similar perspective views of a modified form of separator.

F ig. 8 is a perspective view of a modified form of separator.

Fig. 9 is a perspective view of a modified form of separator.

Fig. 10 is a view showing the form of separator shown in Fig. 9 in end elevation.

The type of separator shown in Figs. 4: and 5 is for use in connection with a concentrating jig of the type illustrated in Figs. l, 2 and 3. This is a well known type of concentrating jig and therefore the details of the jig have notjbeen illustrated and will not be specifically described. This jig comprises in brief, a body l which is divided -into compartments 2 positioned in stepped relation to each other as shown in Fig. 2 and each compartment having a transverse partition 3 providing an auxiliary chamber 4 in which a piston 5 moves so that water which fills the chambers may he forced up through the screening 6 provided between the partitions 3 and the outer walls of the compartments or cells 2.

The separator shown in each of these compartments 2 will have the construction shown 1n Figs. 4 and 5 and from an inspection of these figures, it will be seen that each separator is provided with a housing 7 which is triangular in shape and provided with an extension or hollow arm 8 having a head 9 at its outer end and-along its upper edge provided with a tongue 10 for engaging the upper edge of the side wall of the compartment and suspending the separator with the outer walls of the housing and arm resting upon the screen. The inner walls 7 and 8 of the housing and arm are cut short ot the lower edges of the outer walls so that when the separators are in place there will be a space lett between the screen and the inner walls of the housing and arm through which the concentrates may pass into the arm and housing. It should be noted that the lower edges of the inner walls terminate in a plane intermediate the lower edges oit' the outer walls andthe outlet 11 which registers with the outlet 12 inthe wall of the ig. A driving plate 13 is carried by the outer wall of thehousing 7 and provided with an opening 14 positioned in alinement with the opening 11 and a door or closurepl'ate 15 which is provided with an opening 16 is slidably mounted between this driving plate 13 and theouter wall of the housing 7 and provided with a bent upper end portion forming a tongue extension 17 'for engagement by an actuating rod 18 so that the closure plate may be moved to bring the opening 1G into and out of' registry with the openings 11 and lt'and thus control the passage ot' material from the housing intoV the spout 19 `which extends over lthe trough 20.

When the jig is in operation7 the piston 5 moves vertically and the water is forced up through the screen 6 when the piston moves downwardly and when the piston moves upwardly upon the return stroke, the water moves v downwa 1dly through the screen. Therefore, the water is caused to pulsate through the screen and washes through the ground ore which is placed upon the screen. The Vheavy ore or concentrates will settle in the compartment and the refuse and relatively light roek will remain upon the top of the mass. The concentrates will gradually work beneath the -lower edges of the inner walls 7 fand 8 and upon the water moving upwardly through the screen,v the concentrates in the housing will be carried through the outlet and will pass through the chute 19 and drop into the trough 20.

. The refuse passing from one compartment lore adhering thereto will have been sepa-V to another and the same process of separation is repeated so that by thel time the refuse has reached the last compartment'in the-jig, all -o'I' the good ore and roel; having rated from the refuse. It will thus be seen that this form of separator is so constructed that it may be used in connection with a conventional type ot jig and the dead ore and ore carrying rock readily separated from the trash.

In Figs. (3 and 7 there has been shown a modified construction of separator in which a central housing 21 is disposed between end housings 22 and connected with the end housings by arms 23 having tongue extensions `2t for suspending the separator from the wall of a jig chamber. The central heusing'21 has its outer wall or end wall provided with an outlet 25 and the end housings 22 have their outer side walls provided with outlets 2G. rlhe inner walls terminate short of the lower edges of the outer walls so that space will be left between the inner walls and the screen upon which the outer walls will rest. ln Fig. 8 there is shown a separator very similar to the torni shown in Figs. (i and 7 but somewhat smaller, the housing 21 being omitted and the housings 22 which are provided with the outlets 2O connected by the arms 23 which carry the supporting tongue or lip '24. This is also used in the same manner as previously explained. In the form shown in Figs. E) and 10, the end housings 22 are omitted and the arms 28 which extend from the housing` 21 are somewhat elongated. The types oilijigs in which the modified forms of separators are used have not been illustrated since they are of a conventional construction and the separators are simply put in place with the outlets registering with the outlets of the compartments.

I claim 1. A separator comprising a housing hav ing an outlet intermediate its height, and a hollow arm extending from the housing and communicating with the interior thereof, the arm and housing each having an inner wall terminating intermediate the level of the outlet, and the level of the lower edge of its outer wall.

2. The structure oi claim 1 and a tongue extending from the arm for engaging the upper edge of a jig wall and suspending the separator.

In testimony whereof l have hereunto set my hand.
